Y Application tiled May 16, 1902. Serial No. 107,656. (No model.)

vuseful Improvements in Coke-Ovens; and I do hereby declare thefollowing to he a full, clear, and exact description of the invention,

such as will enable others skilled in the art to which it appertains tomake and use'the same.

My invention relates to certain new and useful improvements incoke-ovens.

In the accompanying drawings, Figure l represents a perspective view ofa coke-oven embodying my invention, said view being partly in sectionand with the oven-door removed. Fig. 2 represents a horizontalcrosssection, partly broken away, of a bench of ovens embodying myinvention, the middle oven of the series showing the oven-doorwithdrawn.y Fig. 3 represents a front elevation of the same.

Similar numerals of reference indicate similar parts throughout theseveral views.

The main characteristic feature of my invention consists in providing aU- shaped Iioor for the oven, while retaining the dome shape of thepresent beehive oven. I therefore preserve all the advantages ofthe-beehive oven-such, for instance, as its'good coking qualities-butdispense with the small door in the front part thereof, providing inlieu of said door a door equal in width to the full width of the oven,thereby facilitating the discharging of the coke from the oven.

The perspective view shownin Fig. 1 of the drawings illustrates one-halfof the dome 1 of the oven and one-half of the outlying superstructure,this view being chosen to more graphically delineate the relation of theparts to each other. The iioor or bottom 3, as will be readily seen, isU-shaped,widening slightly toward the discharge end. The front part 5 ofthe superstructure may be sustained (in addition to the support given bythe piers 15) by the door-frame 4,whioh extends across the full face orwidth of the oven-chamber and which may be made of ironor other suitablematerial. The top 14, rear part 2, and side walls of the superstructure,and the top, rear part, and side walls of the dome derive their supportdirectly from the foundation 6.

The front wall of the dome is supported upon a curved beam 30, supportedat its ends upon Vpedestals 32, of brickwork, from which the walls 12extend forwardly. The beam 30 is joined to the top of the adjacentdoor-frame beam 31 by a connecting-plate 33 and rivets 34, as shown. l 4

The door consists of the casting 7, having hollow interior spaces 9.Fastened to said casting and projecting outwardly is a plurality ofeyebolts 11 for the purpose of readily withdrawing the door from thedoor casing or frame 4. In the rear side of the door,whicl1, it will'benoted, is curved, is a series of firebricks or tiles 8.

On the upper portion of the casting 7 is hinged the supplementary door13 on hinges 20, as shown in Fig. 3. Preferably on the lower edge of thedoor 13 I outa longitudinal slot' or aperture 24 for a purposehereinafter described. 21 indicates a knob to open the door 13.

The operation vof the oven is substantially as follows: The door 7 beingin place within its casing 4, thereby closing the oven, and the'chargehaving been coked and being ready to sprinkle, the loperator by means ofthe knob 21 opens the supplementary door 13, so as to be able to inserta sprinkling device for sprinkling the charge. After the coke has beensprinkled the door 7 is withdrawn by means of the eyebolts 11 and isApushed to one side, thereby exposing the interior of the oven for litsfull width. The coke can now be very readily and quickly withdrawn.After the withdrawal of the coke the door is reinserted in the doorcasing or frame 4, and the new charge of coal to be coked is dropped, asusual, into the oven through its trunnel-hole. The supplementary door 13being down, the operator can readily level off the charge. Thesupplementary door 13 is then raised, and the coking of the charge isproceeded with. Ventilation is regulated by the amount of space leftopen for the pasq sage of air through the Ventilating-slot 24.

It will be understood that before charging. the oven and preliminary tothe coking operation I insert in the oven a flexible iron band, of awidth somewhat less than the heightA of the door-openingthe band beinginserted in such manner that its free ends Vioo are adjacent to thedoor-opening, while its main body portion lies along the periphery ofthe lower or charge-containing portion of the oven. This flexible bandfurnishes means for quickly discharging the coke through the doorwithout obstruction, my invention thus presenting facilities forobtaining beehiveoven coke and at the same time having a capacity forspeedy, complete, and clean discharge of the product.

So far as I am aware, it is broadly new to provide a beehive coke-ovenwith a U -shaped floor and to thus combine the good coking qualities ofthe beehive oven with the facility of discharging characteristic of theold Welsh oven. I desire, therefore, that my broad claims should have aninterpretation commensurate with this generic feature of novelty.

Having th us described my invention, what I claim, and desire to secureby Letters Patent, is-

1. A coke-oven, provided with a vaulted roof of the beehive type andhaving a U- shaped floor, and a door removable along said lfloor, theinner face of said door conforming in curvature to the inner peripheryof the oven; substantially as described.

2. A coke-oven, provided with a vaulted roof of the beehive type andhaving a U- shaped iioor and a door therefor as wide as the Widest partof the oven-floor;substan tially as described.

In testimony whereof I alix my signature in presence of two witnesses.

GEORGE FRANCIS MYERS.
